Apex ARC-8RT 17x8.5 Fully Forged Touring Wheel (ARC8RT1785ET40-5120-7256-AN) - BMW
The Apex ARC-8RT brings one of the most iconic BMW wheel designs ever created into the modern forged era. Designed specifically for enthusiasts who demand lightweight performance, track-ready durability, and timeless styling, this 17x8.5 forged Touring Line wheel delivers significantly improved strength, stiffness, and impact resistance compared to traditional flow formed alternatives. Finished in Anthracite and engineered around BMW-specific fitment requirements, the ARC-8RT blends OEM+ styling with motorsport-level engineering.
Built using fully forged 6061-T6 aluminum and formed under an immense 10,000 tons of pressure, the ARC-8RT offers enhanced grain structure and reduced porosity for exceptional structural integrity. Apex redesigned the spoke architecture with thinner yet deeper spokes to improve rigidity without compromising weight or brake clearance. Combined with the reinforced Sprint Spec inner lip and vehicle-specific barrel profile, this wheel is engineered to handle everything from aggressive street driving to repeated track abuse while maintaining the clean, classic ARC-8 appearance BMW enthusiasts love.
